Samuel L. Jackson lost his virginity aged 11.
The 64-year-old star used to go skinny dipping in a small stream while he was on holiday at a relative's farm in Georgia, US, with girls who were a little older than he was, and he was willing to "do that thing" as long as they consented.
He told Playboy magazine: "There was a family of girls who lived through the woods from us, and we all used to meet at this creek and swim naked.
"I was about 10 or 11. I think two of the girls were about 14, 15, so that's when it happened.
"Girls were interesting to me, period. They could be fat, skinny, tall, short, ugly, beautiful - as long as they were willing to do that thing."
The star has been married to actress LaTanya Richardson since 1980 after the pair met while he was at the all-male Morehouse College, Atlanta, while she was Spelman College which was based in the same city.
Two years after they wed, they had their only child, daughter Zoe, together.
